SAFETY PRECAUTIONS
WARNING:
IN GENERAL
When using rotating head cutting equipment, basic safety precautions should always
be followed to reduce the risk of personal injury.
Operate this tool only in accordance with specific operating instructions.
Do not override the deadman switch on the power unit. Locking down, ob-
structing, or in any way defeating the deadman switch on the power drive unit
may result in serious injury.
DRESS CONSIDERATIONS
Use standard safety equipment. Hard hats, safety shoes, safety harnesses, protec-
tive clothes, and other safety devices should always be used when appropriate.
Use safety glasses. Do not operate cutting tools without eye protection.
Dress properly. Do not wear loose clothing or jewelry. They can be caught in rotat-
ing and moving parts. Avoid slippery floors or wear nonskid footwear. If you have
long hair, wear protective hair covering to contain it.
WORK AREA
Keep the work area clean. Cluttered work areas and benches invite injuries.
Consider the work area environment. Keep the area well lit. Keep electrical cords,
cables, rags, rigging straps, and etc. clear of rotating equipment. Do not use power-
cutting tools in the presence of flammable liquids and gasses.
Keep visitors away. Do not let visitors or untrained personnel at or near operating
tools. Enforce eye protection requirements for all observers.
Do not over reach. Keep proper footing at all times.
Stay alert. Watch what you are doing. Use common sense. Do not operate tools
when you are tired.

TOOL CARE
Maintain tools with care. Keep tools in good operating condition. Sharp tool bits
perform better and safer than dull tool bits. Well maintained tools function properly
when needed.
Check for damaged parts. If a tool has malfunctioned, been dropped or hit, it must
be checked for damage. Run no-load tests and feed function checks. Do a com-
plete visual inspection.
Electric motors. Use only with proper AC voltage power sources and observe all
normal electric shock hazard procedures.
Do not abuse power and control cords. Pulling or running over cords and cables
can result in electrical shock hazards and malfunctions. Keep control and power
cords out of all cutting fluids and water.
Hydraulic drives. Observe proper procedures for electrically driven power sources.
Avoid damage to hydraulic lines. Keep quick-disconnects clean. Grit contamination
causes malfunctions.
Air tools. Check the exhaust muffler. Broken or damaged mufflers can restrict air
flow or cause excessive noise. Use air motors only with a filtered, lubricated and
regulated air supply. Dirty air, low-pressure air or over pressure air will cause mal-
functions, including delayed starting.
AREA EQUIPMENT
Secure work. Whenever possible use clamps, vises, chains and straps to secure
pipe.
Make sure the tool is secured; it is safer to have both hands free to operate the tool.
TOOL USE
Use the right tool and tool bit for the job. Do not use a tool, which is incorrect for the
job you are doing.
Keep the tool bits fully engaged in the tool bit holders. Loose bits are a safety haz-
ard.

Model 300 MICROFACER™
92-0756 : Rev. 060811
Disconnect power supply during setup and maintenance. Use all ‘Stop’ or Shut off’
features available when changing or adjusting tool bits, maintaining the tool, or when
the tool is not in use.
Remove adjusting keys and wrenches before applying power to the equipment.
Develop a habit of checking the tool before turning it on to make sure that all keys
and wrenches have been removed.
Do not force tools. Tools and tool bits function better and safer when used at the
feed and speed rate for which they were designed.
Do not reach into rotating equipment. Do not reach into the rotating head stock to
clear chips, to make adjustments, or to check surface finish. A machine designed to
cut steel will not stop for a hand or an arm.
Handle chips with care. Chips have very sharp edges and are hot. Do not try to pull
chips apart with are hands; they are very tough.
Avoid unintentional starts. Do not carry or handle tools with your hand on the oper-
ating switches or levers. Do not lay the tool down in a manner that will start the
drive. Do not allow the tool to flip around or move when adjusting or changing tool
bits.
Store idle tools properly. Disconnect tools from the power source and store in a safe
place. Remove tool bits for safe handling of the tool.

NOTE:
MAINTENANCE
All components should be cleaned and coated with a light film of oil prior to use.
Use a clean, non-detergent oil, preferably SAE 10 (90 SSU) or lighter.
When the Model 300 is operated in the vertical position, cutting head up, it should
be turned upside down and the chips and/or other debris removed after each tube
squaring operation has been completed.
Tool life may be severely shortened, unless chips and/or other debris that
have been deposited on the cutting head during the machining operation are
removed.

OPERATION
Read the Operating Instructions carefully before attempting to operate the Model
300 MIROFACER™Tube Squaring Tool.
Use eye protection at all times when operating Model 300.
INSTALLING THE SADDLE SET
Select the saddle set which is the proper size for the OD of the tube which is to be
machined.
Squeeze the saddle set to compress the springs and insert the saddle set into the
front of the Model 300.
Retain the saddle set by inserting the two (2) cap screws into the front of the saddle
set.
INSTALLING THE TOOL BIT
Select the tool bit to be installed.
Slide the tool bit into the slot on front of the main shaft.

INSTALLATION
Slide the tube to be worked on into the saddle, leaving approximately 1/8” (3 mm)
between the tool bit and the end of the tube.
INSERT IMAGE
Tighten the saddle set by turning the clamp knob below the saddle set.
MACHINING SEQUENCE
Turn the motor on and let it slowly rotate to ensure that the tool bit does not make
contact with the end of the tube at this time.
Loosen the clamp knob to release the saddle set and remove the machined tube.

CUTTING SPEEDS AND FEEDS
Use 200 surface inches per minute (5080 surface millimeters per minute) for:
Stainless steels in general when no coolant is allowed, all heavy-wall tube
and some chrome/molybdenum steels.
Use 250 surface inches per minute (6350 surface millimeters per minute) for:
Mild steels and some thin-wall stainless steels when coolants are permitted
and applied.
Use 300 surface inches per minute (7620 surface millimeters per minute) for:
Aluminum and some thin-wall mild steel and tube with coolants.
BASIC FEED RECOMMENDATION
Use very light feed for initial beveling or until a continuous cut is established.
This is very important for longer tool bit life when cutting through flame cut or out of
square pipe ends.

Use adequate feed, .003” to .006” (.08mm to .15mm) per revolution thereafter, to
establish a continuous chip cut.
If the feed is too light, only light stringer chips will be removed.
If the feed is too heavy the drive will start to overload and the chip will start to
have a rough or torn appearance.
